The blocks in the next upper horizontal layer will be laid upon the upper flat face of the wall thus produced, and the longitudinal air vent or passage I'll will provide the desired circulation. The longitudinal passage 2| beneath the layer of transverse bricks also provides the desired circulation.

The .15

invention herewith shown and described are rto be taken as preferred examples of the same and that various changes in the shape, "sizeandjarrangement of parts, may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims. i I

Having thus described my invention, what I claim is: r

1. A building block having a main recess at one longitudinal corner-for providing a vertical lonf gitudinal extensiorflsaidblock being provided at its ends "with locking recesses extending through the top and bottom" thereof, said" block being provided upon one horizontal'face with'a longitudinal vent recess, said block being provided in its vertical extension-With an intermediate lockingrecess and saidbldck having' a' vertical vent longitudinally of the block beyond the-end or the intermediate locking'recess'fora substantial distance, the locking-recesses being adapted to receive vertical keys.

2. A building block having a main recess at one longitudinal corner for providing'a vertical longitudinal extension, said blockbeing provided at its ends with vertical locking recesses, said block being provided upon its horizontal face remote from the main recess with a longitudinal vent groove, said block being provided in its vertical; extension with an intermediatelocking recess, said block having 'a verticalvent passage extending longitudinallybf the blockandprojecting beyond one end of' the intermediate looking recess for a substantial distance, the vertical vent passage beingdispo sed upon one side of' the intermediate locking recess. 1'

3. A building block having a; main' recess at one longitudinal corner for providing-a vertical longitudinal extension, said blockbeing provided in its endswith vertical locking recesses extending through the top'andbottom' thereof, said block being provided upon its horizontal face remote from the main-recess with a longitudinal vent recess leading into the end locking recesses,

said block being provided upon its horizontal face adjacent to the main recess with a longitudinal vent recess leading nto the vertical end locking communicating with the vertical and horizontal 'injco'mmunication with Vertical intermediate zontal ventilating grooves.

recesses, the longitudinal vent recesses providing between them reduced hand-engaging portions, said block being provided in its vertical extension with an intermediate lockingrecess having its inner end closed, said block being also provided with a vertical vent opening extending longitudinally thereof beyond the end of the intermediate locking recess, the vertical vent opening longitudinal vent recesses. I

4. A wall comprising horizontal la ters of blocks, the blocks in one layer being a1 ranged to break joint with the blocks in the next layer and the blocks in one layer being inverted with respect to the blocks in the next layer, each block ,having amain recess in one longitudinal corner,

each block having vertical locking recesses in its ends and an intermediate locking recess, each blockhaving a vertical vent opening extending longitudinally beyond the end of the intermediate idckingrecess for a substantial distance, and keys held within the locking recesses, the vertical vent openings extending beyond the sides of the keys to permit of ventilation.

' 5. A generally L-shaped building'block having portions forming a main longitudinal recess, the block being provided in its ends with vertical recesses, said vertical portion being provided with an intermediate vertical recess, the horizontal portion being provided with upper and lower longitudinal ventilating grooves the end recesses.

6; An L-shaped building block comprising horizontal and vertical portions aifording a main longitudinal recess,
